When was your mixer made?

Did you ever wonder when Bosch made your mixer? It’s been a topic of discussion on the Mixer-Owners Yahoo Group recently, with some talk back and forth with the Bosch importer, L’Equip.

On the bottom of your mixer, you should find a sticker with an “FD Number.” It will be in the form of the letters “FD” followed by 4 numbers: FDxxxx.

The last two numbers correspond to the month the mixer was made. 01 would be January, 12 would be December. That’s the simple part. To determine the year requires math.

The math goes something like this: add 20 to the first two numbers in the “FD Number” and the last two numbers of that number correspond to the last two numbers of the year. Got that?

Let’s take FD7909 as an example. 79 + 20 is 99, so FD7909 was made in September of 1999.

How about FD9104? 91 + 20 is 110, so we take only the last two numbers and come up with 2010. FD9104 was made in April of 2010.

I don’t like math. Never did. Let’s make a chart!

Note: I continued this chart back to 1980 and forward to 2019. There was a model change in 1984, so it makes sense that this chart will not be accurate before 1984, and, of course, I can’t guarantee it will be accurate in the future.
